Abstract: A bicycle helmet is provided having (a) a structural foam liner, (b) a plastic shell overlay the liner and having a transparent zone and an opaque zone, (c) an electroluminescent lamp film located between the liner and the shell and positioned to emit light from the transparent window, (d) a battery and (e) an inverter. The battery and inverter are housed in pockets on opposite sides (left, right) of the helmet for providing a weight balanced helmet. The battery is an electrical communication with the inverter for supplying direct current thereto. The inverter converts the direct current to alternating current and is in electrical communication with the film for causing light to be emitted therefrom. The cover units for the pockets are preferably shaped for desirable aerodynamic, structural and aethestic properties.
